Question

The cost of fencing around a square field is $ 12000 . If the cost of fencing per metre is $ 20 , find the perimeter of the square field.​

Answer 1

Step-by-step explanation:

Cost of fencing per metre = Rs 20

Total cost of fencing = Rs 12000

So, the length of fencing (perimeter) = Total cost/ Cost per metre

= 12000/20

= 600 m

Now, length of fencing = Perimeter of the square field

= 4 × side of the field

Therefore, 4 × side of the field = 600 m

or, side of the field = 600/4 m = 150 m

So, area of the field = 150 m × 100 m = 15000 sq m.
